Release notes

Overview

Editorial synthesis with inline references and a source ledger when citations are available.

Release overview

tvOS 11 launched on September 19, 2017 with Apple TV 4K display support, expansion of the Apple TV app, synchronized Home screens, iOS Control Center remote access, automatic AirPods connection, adaptive appearance, right-to-left scripts, broader braille-display support, and a new security baseline.[1][2][3][4]

Evidence boundary

The tvOS software release preceded Apple TV 4K hardware availability on September 22. Hardware-dependent 4K and HDR capabilities are described as tvOS 11 support on Apple TV 4K, not as features usable on every Apple TV on September 19.[5][6]
